Description

Technical Field

[0001] This utility model belongs to the field of laser engraving technology, and in particular relates to a novel fixture for laser engraving. Background Art

[0002] Laser marking technology, as an important technology in the field of modern precision machining, has been widely used in many industries such as electronics, machinery, automobiles, and aerospace due to its ability to precisely etch or mark material surfaces with high-energy laser beams. This technology can not only produce high-precision markings, serial numbers, QR codes, and other patterns or text, but also, with the continuous development of technology, higher requirements are placed on the precision, efficiency, and safety and cleanliness of the working environment.

[0003] In the laser engraving process, the fixture, as a key component for supporting and precisely positioning the workpiece, directly affects the quality of the engraving results and production efficiency due to its rational design and functionality. Currently popular laser engraving fixtures mainly consist of a fixed frame, a worktable, and a simple clamping device. These fixtures secure the workpiece to the worktable manually or mechanically to ensure stability during the engraving process.

[0004] However, in practical applications, the limitations of existing laser engraving fixtures have gradually become apparent:

[0005] First, the clamping devices of existing fixtures often use mechanical clamping or simple gravity clamping, which makes it difficult to accurately control the clamping force and easily leads to uneven force on the workpiece and deformation. In particular, most of the workpieces that need to be engraved are thin plates or easily deformable materials.

[0006] Secondly, the laser engraving process generates a large amount of fumes, which may contain harmful substances that pose a potential threat to the health of operators and may pollute the working environment. However, existing fixtures lack a fume collection structure, causing the fumes to be directly emitted into the air, which not only threatens the health of operators but also affects the cleanliness of the working environment.

[0007] Therefore, it is essential to invent a new type of fixture for laser engraving. Utility Model Content

[0008] The purpose of this invention is to provide a novel fixture for laser engraving, which solves the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a novel laser engraving fixture, comprising a mounting plate, a fixed frame, a sliding frame, a clamping mechanism, a cylinder, a worktable, and a suction mechanism. The fixed frame is bolted to one end of the upper side of the mounting plate, and the sliding frame is slidably mounted on the upper side of the mounting plate via a sliding track and a slider. A clamping mechanism is fixed to both the fixed frame and the sliding frame. Both sides of the sliding frame are bolted to the output ends of corresponding cylinders, and the cylinder bases are bolted to the upper side of the mounting plate. A worktable is bolted to the upper middle part of the mounting plate, and the worktable is positioned below the fixed frame and the sliding frame. Suction mechanisms are provided on both sides of the worktable, with their ends fixed to the corresponding fixed frame and the sliding frame respectively by bolts.

[0011] Furthermore, the clamping mechanism includes a lifting plate, an electric push rod, and a rubber pad. The upper sides of both ends of the lifting plate are fixed to a fixed frame or a sliding frame by the electric push rod, and the lower side of the lifting plate is fixed with a rubber pad by screws. This arrangement can limit the two ends of the workpiece to be engraved.

[0012] Furthermore, the rubber pad has through holes inside, and a mesh-like rubber structure is fixed inside the through holes. This design can prevent deformation of the workpiece that needs to be engraved.

[0013] Furthermore, the extraction mechanism includes an extraction pipe, a first limiting frame, a sleeve, a second limiting frame, and an auxiliary frame. The extraction pipe is fixed to the fixed frame via the first limiting frame, and several extraction holes are provided on the side of the extraction pipe near the worktable. One end of the extraction pipe is connected to an external gas treatment device via a connector, and the other end of the extraction pipe is slidably disposed inside the sleeve. The sleeve is a pipe body sealed at one end, and the outer side of the sleeve is fixed to the sliding frame via the second limiting frame. The sleeve slides through the auxiliary frame, which is fixed to the mounting plate by bolts. This arrangement allows for the treatment of fumes generated during workpiece engraving in conjunction with the external gas treatment device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The clamping mechanism of this utility model precisely controls the movement of the lifting plate through an electric push rod, thereby achieving stable positioning of both ends of the workpiece. This design not only ensures the positional stability of the workpiece during the engraving process, but also effectively avoids workpiece deformation caused by excessive clamping through the elastic deformation of the rubber pad. The grid-like internal structure of the rubber pad further enhances its adaptability and buffering capacity, providing more uniform and gentle support for the workpiece.

[0016] 2. The exhaust mechanism of this utility model can treat the fumes generated during workpiece engraving by cooperating with external gas treatment equipment and exhaust pipe. Secondly, when the distance between the sliding frame and the fixed frame is adjusted according to the size of the workpiece, the sleeve can adjust the wrapping length of the exhaust pipe accordingly to wrap the excess exhaust holes on the exhaust pipe, thereby maximizing the exhaust efficiency and avoiding the waste of gas extraction force caused by too many exhaust holes.

DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] Please see Figure 1 As shown, this utility model is a novel laser engraving fixture, including a mounting plate 1, a fixed frame 2, a sliding frame 3, a clamping mechanism 4, a cylinder 5, a worktable 6, and an air extraction mechanism 7. The fixed frame 2 is fixed to one end of the upper side of the mounting plate 1 by bolts, and the sliding frame 3 is slidably mounted on the upper side of the mounting plate 1 through the cooperation of a slide rail and a slider. The clamping mechanism 4 is fixed on both the fixed frame 2 and the sliding frame 3. Both sides of the sliding frame 3 are fixed to the output end of the corresponding cylinder 5 by bolts, and the base of the cylinder 5 is fixed to the upper side of the mounting plate 1 by bolts. The worktable 6 is fixed to the upper side of the middle part of the mounting plate 1 by bolts, and the worktable 6 is set under the fixed frame 2 and the sliding frame 3. The air extraction mechanism 7 is provided on both sides of the worktable 6, and the two ends of the air extraction mechanism 7 are fixed to the corresponding fixed frame 2 and the sliding frame 3 by bolts respectively.

[0026] like Figure 2 As shown, the clamping mechanism 4 includes a lifting plate 41, an electric push rod 42, and a rubber pad 43. The upper sides of both ends of the lifting plate 41 are fixed to the fixed frame 2 or the sliding frame 3 by the electric push rod 42. The lower side of the lifting plate 41 is fixed with a rubber pad 43 by screws. After the workpiece to be engraved is placed on the worktable 6, the lifting plate 41 can be moved down by the electric push rod 42, thereby limiting the two ends of the workpiece to be engraved.

[0027] Specifically, the rubber pad 43 has a through hole inside, and a mesh-like rubber structure is fixed inside the through hole. When the lifting plate 41 moves down and squeezes the workpiece to be engraved, the rubber pad 43 can deform accordingly, thereby preventing the workpiece to be engraved from deforming.

[0028] like Figure 3 As shown, the suction mechanism 7 includes a suction pipe 71, a first limiting frame 72, a sleeve 73, a second limiting frame 74, and an auxiliary frame 75. The suction pipe 71 is fixed to the fixed frame 2 via the first limiting frame 72. Several suction holes are provided on the side of the suction pipe 71 near the workbench 6. One end of the suction pipe 71 is connected to an external gas processing device via a connector, and the other end of the suction pipe 71 is slidably disposed inside the sleeve 73. The sleeve 73 is a tube sealed at one end, and its outer surface is connected to the sliding frame 3 via the second limiting frame 74. The sleeve 73 slides through the auxiliary frame 75, which is fixed to the mounting plate 1 by bolts. In use, the sleeve 73 can treat the fumes generated during workpiece engraving by cooperating with the external gas treatment equipment and the exhaust pipe 71. Furthermore, when the distance between the sliding frame 3 and the fixed frame 2 is adjusted according to the size of the workpiece, the sleeve 73 can adjust the length of the sleeve covering the exhaust pipe 71 accordingly, covering the excess exhaust holes on the exhaust pipe 71, thereby avoiding the waste of gas extraction force of the external gas treatment equipment.

[0029] Please see Figure 1-3 As shown, this utility model is a novel fixture for laser engraving. Its working principle is as follows: When in use, the workpiece to be engraved is first placed on the worktable 6. Then, according to the size of the workpiece, the distance between the sliding frame 3 and the fixed frame 2 is adjusted by the cylinder 5. Next, the two ends of the workpiece are limited by the clamping mechanism 4, so as to facilitate the engraving of the workpiece. In addition, during the engraving process, the fumes generated during the engraving process can be treated by the cooperation of the air extraction mechanism 7 and the external gas treatment equipment.
